|discussion=<p><i>Rhynchostegium serrulatum</i> can be recognized in the field by its light green color and somewhat complanate foliage. The long leaves with long laminal cells allow rather easy separation from <i>Oxyrrhynchium hians</i>. Sterile collections are sometimes confused with <i>Sciuro-hypnum curtum</i>, but that species usually has conspicuous groups of enlarged alar cells; in <i>R. serrulatum</i> laminal cells are rather homogeneous across the whole base as they are somewhat enlarged and have a specific appearance rather characteristic for this genus. This pattern of leaf base areolation distinguishes <i>R. serrulatum</i> from <i>Brachythecium asperrimum</i>, which is sometimes superficially similar; this Pacific coast species has a small but rather well-differentiated alar group of pellucid cells. In addition, the axillary hairs of <i>R. serrulatum</i> are 3–5-celled, often brownish, while in <i>B. asperrimum</i> they are 2- or 3-celled, short, and pellucid. <i>Rhynchostegium</i> scariosum (Taylor) A. Jaeger from Mexico differs mainly due to its small plants with stem leaves 0.9–1.3 mm; it might be expected in the southeastern United States.</p>
